Abstract​

This memo is a response to Bill English's Request for Comments: 28. It argues that a "millisecond" clock should be satisfactory for most network measurements, since round-trip message transit times are typically at least on the order of tens to hundreds of milliseconds. It notes that the IMP contains a 16-bit hardware clock incremented every 100 microseconds, used for timing internal events within the IMP, for example during tracing, while most measurements are made using a 25.6 ms. software clock.
